-She ends up becoming Saito's maid.
-Snaps Louise from her suicidal state-And... the books she read at times...?
That's all I can remember clearly that are stand-out developments...
The rest of her roles is basically romance with Saito, trying to seduce Saito, normal days with Saito (and Louise), the normal stuff.

Her role has been nothing to little recently, since the past volume or two have been focused in Romaria.
Siesta~~~

It would make things interesting if Siesta was to be the last Familiar.
